In the pharmaceutical industry, the selection of excipients is as critical as the active pharmaceutical ingredient (API) itself. These inactive substances play vital roles in drug formulation, affecting everything from bioavailability to stability and ease of administration. Stearic Acid (CAS 57-11-4), a saturated fatty acid, stands out as a highly valuable excipient due to its diverse functionalities. As a trusted manufacturer and supplier of pharmaceutical-grade chemicals, we are committed to providing the high-purity Stearic Acid necessary for developing safe and effective medications.

Stearic Acid's chemical properties make it an excellent choice for various pharmaceutical applications. It is commonly used as a lubricant in tablet manufacturing, preventing powders from sticking to machinery and ensuring smooth tablet ejection. It also acts as a binder, helping to hold the tablet ingredients together, and in some cases, it can aid in the controlled release of the API.

Key Pharmaceutical Applications:

  • Tablet Lubrication: During tablet compression, the friction between the powder blend and the punches/dies can cause sticking and damage to equipment. Stearic Acid, when incorporated into the tablet formulation, acts as an effective lubricant, reducing this friction and ensuring efficient production. Our pharmaceutical-grade Stearic Acid is ideal for this purpose.
  • Binder and Granulating Agent: Stearic Acid can improve the flowability of powders and act as a binder during the granulation process, helping to form uniform granules that are suitable for tableting.
  • Controlled Release Formulations: In some extended-release drug delivery systems, Stearic Acid can be used to form matrices that gradually release the API over time, improving patient compliance and therapeutic outcomes.
  • Topical Preparations: It also finds use in ointments, creams, and suppositories, where its emollient properties contribute to product texture and skin compatibility.

Ensuring Pharmaceutical Quality and Supply

For pharmaceutical manufacturers, sourcing an excipient like Stearic Acid requires stringent quality assurance. We understand the regulatory landscape and the critical need for purity and consistency. Our manufacturing processes are designed to produce Stearic Acid that meets or exceeds pharmacopoeial standards (e.g., USP, EP, BP). As a reliable supplier based in China, we ensure a robust supply chain to meet your ongoing manufacturing demands.

We offer competitive pricing for bulk purchases of pharmaceutical-grade Stearic Acid, making it an economically viable choice for your formulation needs. If you are looking to buy high-quality Stearic Acid for your pharmaceutical products, partnering with us provides the assurance of quality, reliability, and cost-effectiveness.
